But the conservative political commentator has maintained an active presence on social media, and he recently found a new way to interact with fans: by giving them vocabulary tips.

O'Reilly has posted a "word of the day" several times this month, introducing his 2.5 million followers to a new vocabulary item. Although he doesn't define the words, O'Reilly invariably warns his readers to not exemplify the word in question when they email him, and then provides his email address.

The "word of the day" series seems to be one of multiple efforts by O'Reilly to engage with internet users since losing his Fox News platform. The commentator also publishes life advice in his "Tip of the Day" Twitter posts, and has maintained a weekly conservative-slanted news quiz on his website.

In any case, here are the words O'Reilly wants you to know:

Ignominious — deserving or causing public disgrace or shame

mooncalf — a foolish or absentminded person

blatherskite — a person who talks at great length without making much sense
